Application of microwave chaotic signal in advanced detection of coal mine water inrush

Abstract

In view of problem that traditional method for advanced detection of coal mine water inrush cannot improve detection depth and resolution simultaneously, a method taking microwave chaotic signal as radar detection source was proposed. The method takes 580 MHz chaotic signal generated by Colpitts circuit as detection source, then applies it to advanced detection of coal mine water inrush, so as to get resolution of 5.5 cm unrelated to detection range, which improves detection accuracy.
